In this screenshot ^ it says "Payment Required". Do you have enough credits in Open Router, or whatever you are using to pay for AI? Typically a first prompt with MKStack can cost up to $10 for most Nostr-specific prompt apps we've tested.

I didn't even notice that. This is most definitely the answer.
I didn't have them at first but this screenshot was the retry after adding credits. From here it actually ran the prompt and displayed it's thinking process in console but then stopped for some reason. After researching I found there was an issue with npx path on that windows machine so presumably it was having a hard time actually making any writes because of that. Got off windows and did the same thing on Ubuntu and worked perfectly (other than me trying to paste incorrectly)
